Description

Technical Field

[0001] The utility model relates to the technical field of core batteries, and particularly relates to a core stacking tooling. Background Art

[0002] A core is an electric core formed by a winding method. After the core is wound, it needs to be placed in a material box for material inspection to determine the quality and processing quality of the core. The traditional method is to directly stack the cores in the material box, and structures such as ear tabs are easily impacted and deformed. At the same time, since the core is not hot-pressed and is in a fluffy state, the core is prone to deformation during the stacking process. After stacking multiple layers, there is a risk of the core tipping over, resulting in poor phenomena such as virtual soldering, misalignment, and missed soldering during the ultrasonic welding process, and improvements are needed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a tooling that can place the core and protect structures such as ear tabs, and avoid deformation and tipping of the core in view of the deficiencies in the above background art.

[0004] To achieve the above purpose, the utility model provides a core stacking tooling, which includes a tray. The tray is provided with a placement groove, the size of the placement groove matches the size of the core. An ear tab groove is provided on the left or right side wall of the placement groove, and the ear tab groove corresponds to the ear tab of the core. The ear tab groove is used to accommodate the ear tab after the core is placed in the placement groove. Pick-and-place grooves are provided on the front and rear side walls of the placement groove, and the pick-and-place grooves facilitate the placement of the core by a manual or automatic pick-and-place mechanism or the removal of the core from the placement groove.

[0005] Further, the number of the placement grooves provided on the tray is multiple.

[0006] Further, the placement grooves are arranged in a rectangular array on the tray.

[0007] Further, multiple layers of the trays are stacked on the material box, and the tray is further provided with a positioning structure. A positioning and stable connection is formed between adjacent two layers of the trays through the positioning structure.

[0008] Further, the positioning structure includes positioning columns arranged on the upper surface of the tray and positioning grooves arranged on the lower surface of the tray and matching with the positioning columns. When the trays are stacked, the positioning columns of the lower tray are inserted into the positioning grooves of the upper tray.

[0009] Further, the positioning structure includes positioning pins and positioning holes arranged on the tray. When the trays are stacked, the positioning holes of each tray are aligned one by one, and the positioning pins are simultaneously inserted into all the positioning holes.

[0019] In order to make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the drawings and specific embodiments. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. In addition, the technical features involved in different implementation modes of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "coupled" should be understood in a broad sense. For example, it can be a locking connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] As Figure 1 shown, an embodiment of the present utility model provides a core stacking tooling, including a tray 1, and a plurality of placement grooves 2 are provided on the tray 1. Among them, the size of the placement groove 2 matches the size of the core 3, that is, the placement groove 2 is set according to the length, width and thickness of the core 3 to ensure that the core 3 can be exactly placed in the placement groove 2. At the same time, an ear groove 4 is also provided on the left or right side wall of the placement groove 2. The ear groove 4 is used to accommodate and protect the ear after the core 3 is placed in the placement groove 2, so as to avoid the ear being impacted during transportation.

[0023] Since the size of the placement groove 2 matches the size of the core 3, when the core 3 is placed in the placement groove 2, the placement groove 2 automatically forms a limit on the core 3 in the horizontal plane, so as to ensure that the ear can be accurately located in the ear groove 4 to achieve the purpose of preventing impact damage.

[0024] As a preferred implementation manner, in this embodiment, access grooves 5 are provided on the front and rear side walls of the placement groove 2. When placing the core 3 or taking the core 3 from the placement groove 2 through a manual or automatic access mechanism, the position of the access groove 5 will not cause damage to the core 3 itself, and the convenience of operation is improved, thereby improving the access efficiency.

[0025] It should be noted that, due to the large size of the tray 1, in order to further improve the utilization rate, in this embodiment, a plurality of placement grooves 2 are formed in the tray 1, and the placement grooves 2 are arranged in a rectangular array to make full use of the size of the tray 1 and improve the placement and handling efficiency of the core 3. Of course, in other embodiments, the tray 1 can also be set to be circular or other shapes according to special needs, and the placement grooves 2 can also adopt other arrangement forms.

[0026] It should be noted that when handling the core 3, in order to further improve the handling efficiency, in this embodiment, a form of stacking multiple trays 1 is adopted so that the material box can handle more trays 1 at the same time. Therefore, as a preferred implementation manner, the tray 1 is also provided with a positioning structure, and adjacent two layers of trays 1 form a stable connection through the positioning structure to avoid displacement, dumping, etc. during the stacking and transportation of multiple trays 1.

[0027] At the same time, as Figure 2 shown, in a specific implementation manner of this embodiment, the positioning structure includes positioning posts 6 provided on the upper surface of the tray 1 and positioning grooves 7 provided on the lower surface of the tray 1 and matching with the positioning posts 6. Among them, the positioning posts 6 protrude outwards relative to the upper surface of the tray 1, and the positioning grooves 7 are recessed inwards relative to the lower surface of the tray 1. When the trays 1 are stacked and placed, the positioning posts 6 of the lower tray 1 are inserted into the positioning grooves 7 of the upper tray 1 so that the trays 1 are positioned in sequence, and finally the entire stacked trays 1 can be fixed as a whole.

[0028] In another specific implementation manner of this embodiment, the positioning structure includes positioning pins and positioning holes provided on the tray 1. When the trays 1 are stacked and placed, the positioning holes of each tray 1 are aligned one by one, and all the trays 1 are simultaneously positioned by the positioning pins (and nuts at both ends, etc.) inserted into the positioning holes.

[0029] As a preferred implementation manner, in this embodiment, the positioning posts 6, the positioning grooves 7, the positioning holes, etc. are all arranged at the diagonal positions of the tray 1 to avoid affecting the distribution of the placement grooves 2 or the placement of the core 3, etc.

[0030] In addition, it should be noted that when the trays 1 are stacked and placed, the upper tray 1 can also be regarded as the top cover of the lower tray 1, so that the cores 3 placed in the trays 1 will not move up and down and collide during transportation, further improving the reliability of the transportation of the cores 3. Among them, the top tray 1 can be limited by the structure on the material box or other limiting structures can be set, etc.

[0031] In summary, by using the core stacking tooling provided in this embodiment, the core 3 can be placed in the placement groove 2 of the tray 1, and then the tray 1 can be placed on the material frame, avoiding the problems that the structures such as the tab are easily impacted and deformed and the core itself is also easily deformed when the core 3 is directly placed on the material frame for transportation, as well as the risk of the core 3 tipping over after stacking multiple layers. This improves the reliability of the core 3 transportation, and also improves the transportation efficiency, ultimately improving the battery production quality and reducing the production cost.

[0032] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0033] The above embodiments only represent several implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
